毛细管

Herschell-Buckley model have another name called H-B model, equation form as follows:〓 Rheology equation of broad sense:〓 The equation is to sheat rate:〓 In the flow of the annular interspace of the pipeline:〓 thereinto n'=〓 All of the experiment of this thesis utilize the rheology test-bed, it can test the pressure losses relevant datum, and imitate the hole and carry on the test related to rock bits movement.

Wise通过对消防泡沫流经普通铁管的流动阻力的研究发现，泡沫并没有宾汉模型的屈服值，认为泡沫纯粹属于假塑性流体，其流变模式为： Logμ=logτ〓+alog〓+b Mitchell使用毛细管研究泡沫流动，Mitchell用下式计算τ〓和μ〓：〓而Buckingham-Reiners对泡沫修正了用于管内流动的宾汉塑性模型，形式如下：〓 Herschell-Buckley模型—又称H—B模型，方程形式为：〓广义流变方程：〓剪切速率方程为：〓在环空中的流动时〓其中〓完成本论文的所有工作都是在试验台上进行，在该试验台上可进行与压力损失相关的数据测试，可模拟钻孔进行与岩屑运动有关的测试研究。

Generally, electric-conductivity materials such as metal, conductive polymers, and graphite are coated on the outside surface of the capillary tip followed by the application of an external high voltage on the tip to provide a sufficient electric field to generate electrospray in seathless interface. Thus, the fabrication of the electric-conductivity material on the surface of fused-silica is one of the main issues when using sheathless interfaces.

一般来说通常需要将金属、导电高分子、或石墨等导电材料涂布於毛细管样品出口尖端，外加第二组电压於导电尖端以提供电喷洒时所需要的电场，但如何将导电材料稳定地涂布於矽氧材质的尖端表面一直是此界面探讨的主题之一。
